Replacing the transmission computer:
Remove the automatic transmission computer (see MR 370 mechanical, 23A, Automatic transmission,
Automatic transmission computer, Removal - Refitting).
Refit the automatic transmission computer (see MR 370 mechanical, 23A, Automatic transmission,
Automatic transmission computer, Removal - Refitting).
Establish dialogue with the diagnostic tool.
Use command VP001 Enter VIN.
Run command VP009 Write last After-Sales Service operation date.
Do not carry out any automatic programming if replacing the automatic transmission computer. Automatic
programming is finalised when the vehicle is driven.
In order to optimise the automatic programming before delivering the vehicle to the customer, apply the
"Programming procedure" shown below.
Replacing the hydraulic distributor:
Remove the transmission hydraulic distributor (see MR 370 mechanical, 23A, Automatic transmission,
Hydraulic distributor, Removal - Refitting).
Refit the transmission hydraulic distributor (see MR 370 Mechanical, 23A, Automatic transmission, Hydraulic
distributor, Removal - Refitting).
Replacing the automatic transmission
Remove the transmission (see MR 370,Mechanical, 23A, Automatic transmission, Removal - Refitting).
Refit the transmission (see MR 370, Mechanical, 23A, Automatic transmission, Removal - Refitting).
Establish communication with the diagnostic tool.
Initialise all the programming, use the command RZ009 Self-adapting clearing (Vdiag05 only).
Run command VP009 Write last After-Sales Service operation date.
The self-programming functions are performed when the vehicle is being driven.
In order to optimise the automatic programming before delivering the vehicle to the customer, apply the
"Programming procedure" shown below.
* APV: After-SalesPROGRAMMING PROCEDURE:
Programming conditions:
The automatic gearbox oil temperature should be between 60˚C and 100˚C.
Stationary, engine running, brake pedal depressed:
Engage neutral at least 5 times to consolidate the programming.
While driving:
Engage the same gear at least 5 times (i.e. in the same conditions) to consolidate the programming.
Note:
Gear changes are slow and harsh the first few times the vehicle is driven, until the automatic transmission computer
has carried out its automatic programming.
During upshifts and downshifts, the system analyses variations in oil pressure, components (play in the brakes and
clutches, changes to spring stiffness due to ageing) and input torque, then corrects them in order to maintain the
quality of gear changes.
The system analyses the turbine speed during the 3 phases of drag reduction (selection of Neutral when stationary,
regulation during drag reduction and deselection of Neutral) and corrects this speed by adjusting the converter
lock-up solenoid valve pressure.

VP001: "Enter VIN".
This command permits manual entry of the vehicle's VIN into the computer.
Use this command each time the computer is replaced or (re)programmed.
VP009: "Write last APV* operation date".
Run this command after replacing or removing - refitting the transmission computer and the automatic transmission.
This command is used to enter the date of the last service operation.
Do not carry out any programming operation if replacing a component; automatic programming is carried
out during driving (See Replacement of components, Programming procedure).

NOTESConditions for applying fault finding procedures to stored faults:
The fault is declared present after:
–in the event of open circuit or short circuit+:
–+ after ignition feed,
–oil temperature ≤ - 40 ˚C,
–vehicle speed > 6 mph (10 km/h).
–in the event of short circuit-:
–+ after ignition feed,
–oil temperature > 180 ˚C,
–vehicle speed > 6 mph (10 km/h).
–accelerator pedal > 12.5 % and engine speed > 305 rpm.
(detection time in the event of short circuit- is 10 minutes).

–in the event of open circuit or short circuit+:
Gear change quality is reduced.
lock-up is inhibited.
–in the event of short circuit-:
The transmission operates as if the temperature had increased.
Customer complaint:
–in the event of open circuit or short circuit+:
If the fault occurs while driving, the transmission engages fixed 5th gear.

Use the Wiring Diagrams Technical Note, SCENIC II ph2.
Check that the coolant temperature (see 13B, Diesel injection, EDC16, CP33 M9R 721 Conformity check)
is ≥ - 40 ˚C (the transmission oil temperature sensor is within its operating range).
If the oil temperature ≤ - 40 ˚C, move on to step 1.
If the oil temperature is ≥ - 40 ˚C, deal with the fault; move on to step 2.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.

Step 1:
Start the vehicle, check that engine coolant temperature is ≥ 20 ˚C.
If the fault is stored, deal with the other faults displayed on the diagnostic tool. In the absence of faults, end of
fault finding.
If a fault is still present, deal with it, then move on to step 2.
Step 2:
Look for any damage to the harness and check the condition and connection of the automatic transmission
computer and automatic transmission connectors.
If the connection is faulty and there is a repair procedure (see Technical Note 6015A, Electrical wiring repair,
Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Disconnect the connector from component 119, measure the resistance of the oil temperature sensor
(on the connector of component 119) between the following connections:
●Connection code 5BZ,
●Connection code 5BY.
The resistance should be between:
–4.208 ± 0.42 kΩΩ Ω Ω
at 20 ˚C,
–1.947 ± 0.19 kΩΩ Ω Ω
at 40 ˚C,
–0.988 ± 0.09 kΩΩ Ω Ω
at 60 ˚C,
Is the resistance correct?
If YES, contact the Techline.
If NO, move on to step 3.
Stage 3:
Disconnect connector R22 and check continuity and insulation on the following connections:
●Connection code 5BZ,
●Connection code 5BY.
Between components 119 and R22.
If the connection or connections are faulty and there is a repair procedure (see Technical Note 6015A, Electrical
wiring repair, Wiring: Precautions for repair), repair the wiring, otherwise replace it.
Are the continuity and insulation correct?
If YES, move on to step 4.
If NO, replace the external wiring harness on the automatic transmission.
AFTER REPAIRDeal with any other faults. Clear the fault memory.
Switch off the ignition, wait 1 minute and carry out a road test followed by another
check with the diagnostic tool.

If YES, and if the fault is still present, contact the Techline.
If NO, move on to step 5.
Stage 5:
Drain the automatic transmission (see, MR 370, Mechanical, 23A Automatic transmission, Oil change)
and remove the transmission housing (see, MR 370, Mechanical, 23A Automatic transmission, Hydraulic
distributor).

The resistance should be between:
–4.208 ± 0.42 kΩΩ Ω Ω
at 20 ˚C,
–1.947 ± 0.19 kΩΩ Ω Ω
at 40 ˚C,
–0.988 ± 0.09 kΩΩ Ω Ω
at 60 ˚C,
Is the resistance correct?
If YES, move on to step 6.
If NO, replace the internal wiring harness on the automatic transmission.
Stage 6:
Measure the continuity and insulation of the following connections:
